National Association of Steel Pipe Distributors 2010 Annual Convention February 26, 2010
Loading Pipe on Rail • Safety • Damage • Innovations • Problems • Solutions
Center Beam Cars – Alternative Loads • Too Many Centerbeams, Building Industry down • How to better utilize the asset
Challenges for Alternative Products • Specially designed cars for building products • Load limit considerations • Damage to equipment and future loadings • Load/unload from two sides (tarps) • Centerbeam and height of same cables
TESTING Railway Assn of Canada Impact tested – structural steel, small diameter pipe, rebarField Testing – Limited amount account limited shipper interest BNSF/AAR VTU test procedures using pipe on Centerbeams
Based on AAR Testing Procedures, AAR Open Top Loading Rules Committee: - Approved Rigid Pipe of 12”, 16” and 24” - Did not Approve Smaller diameter “flexible” pipe - Got the opportunity to see Cord Strap perform under dynamic testing More to come.
Pipe Loads in Open TopsUsing Non-Metallic Strapping • Ductile Pipe with Cord Strap • Coated Pipe under test
So How do we solve this? Answer: John Blackman “Non-metallic strapping - Strength of steel with some Elasticity.”
Innovative J hook • Polyester Strapping • Doesn’t Crack/Break as easily • Cost competitive • Virtually eliminated Service • Interruptions • Safer to Use
CordStrap Performance • Initially tested on over 100 loads – no strap breakage • ACIPCO using since January 2009, less than 5 loads with broken straps • ACIPCO Setout Incidence 1st qtr 2009 – 2% • Steel band ductile pipe shippers – 12.3%
Older Figures (pre-1960) • Allows 12-inches of end • clearance • Standard Draft Gear Equipment • Setout incidence up to 16% • Impact Test to determine amount • of load movement
Impact Test Conclusions • Pipe moves more than 12 inches • Repeated impacts, even at low speed • will produce shift over end of cars • Existing Figures need to be changed • in-line with “reality”
Impact Test Conclusions • A timeline has been established to incorporate changes to Figures October 2010 is the target date • AAR TAG is working on the problem
